Actually, I am nt sure the issues with accuracy in most cases is the limits of
the GPS receivers especially since iPhone's use WiFi as additional
triangulation information as much as the OI databases. Since POI databases seem
to have street addresses rather than actual lat/long coordinates, and since the
GIS databases often just give ranges of addresses in a block there is a
significant error rate. My parents home had the largest address on the block
which ended in 32, but some GPS systems suggested it was an address that ended
in 52 and that the address ending in 32 was 300 yards down the street. Google
until last year thought my house was around the corner on a differentt street.
So my hope would be that the checkin process that Square requires would in well
visited areas cause the database to be more accurate.
I remember 5 years ago when I first got Sendaro on my Windows phone, walking
around in circles for 15 minutes because the restaurant I was looking for was
always 100 yards away. I tend to find that happens less often with my iPhone,
if it brings me to the wrong address it pretty much insists on that location
and does not wander around, except for when I am near a body of water.
So the question to get back to the original subject is do people find that they
have less stress finding a location using one of the three blind oriented
iPhone solutions over using a more main stream product?
Best wishes,
Jonathan
